Detailed analysis reveals that mid/late recombination intermediates are moderately reduced, resulting in fewer crossovers and many chromosomes without a crossover. Furthermore, defective chromosome structure is observed, including aberrant histone modifications, defective chromosome ends, precocious release of REC8 from chromosomes and fragmented chromosome axes after pachytene.

Currently, there are no effective treatments available for RI/RI, and oxidative stress is a critical factor that contributes to the associated damage. DJ-1, an important endogenous antioxidant, has been proposed as a promising therapeutic agent for RI/RI owing to its potential for overexpression. In this study, tetrahedral frame nucleic acids (tFNAs) were utilised as an effective delivery vehicle for DJ-1 small activating RNA (saRNA), resulting in the synthesis of a novel nanocomposite (tFNAs-DJ-1-saRNA). In vitro experiments demonstrated that tFNAs effectively delivered DJ-1-saRNA to R28 cells, thus exerting a repair effect on oxidative stress injury. In vivo investigations revealed that the intravitreal injection of tFNAs-DJ-1-saRNA facilitated retinal DJ-1 gene expression and mitigated retinal atrophy induced by RI/RI. Mechanistically, tFNAs-DJ-1-saRNA activated the xCT/GPX4 pathway, thereby inhibiting ferroptosis, reducing ganglion cell damage and protecting the retinal tissue.

Polymeric nanoparticles represent promising drug delivery carriers to the brain due to their unique advantages such as good biodegradability and biocompatibility, flexibility in surface modification and nontoxicity. In addition, the delivery of genetic drugs may stop the progression of neurodegenerative diseases at the genetic level and even avoid the irreversible damage in the central nervous system. In this review, an overview of studies on polymer-based nanoparticles for drug delivery to the central nervous system in typical neurodegenerative diseases, especially Alzheimer's diseases and Parkinson's diseases, is described.

Previous studies showed that club cells and club cell secretory proteins (CCSP) have anti-inflammatory roles, which reduced in COPD. Klotho (KL) decreased in human COPD lung tissue. KL-deficient mice showed aging phenotypes, such as obvious emphysema and premature senility at the early stage, which are characteristics of COPD. However, little is known about the relationship between KL, club cells, and COPD. We speculated lack of KL would aggravate club cell senescence, which contributes to COPD inflammation. We collected COPD lung tissue using single-cell RNA sequencing (scRNA-seq), revealing club cells heterogeneity and cellular senescence in COPD. In addition, KL and CCSP expressions were downregulated in cigarette smoke (CS)-induced COPD mice, associated with increasing age-related markers. After KL knockout, more ciliated cells appeared where club cells disappeared. Furthermore, KL deficiency aggravated club cell senescence and CSE-induced pulmonary inflammation. To investigate the specific regulation mechanism, hnRNPA2/B1 was recognised and identified it was the key molecule in KL-regulated club cell senescence, and neddylation of club cell was a crucial factor contributing to hnRNPA2/B1 downregulation. In vitro, SA-β-gal staining suggested the aging phenotype was aggravated in hnRNPA2/B1-silenced groups, and hnRNPA2/B1 over-expressed achieved a rescue result. Thus, KL could regulate club cell senescence and differentiation. When CS stimulates the small airway epithelium, KL deficiency aggravates lung inflammation, club cell senescence and dysfunctional of ciliated cell. Targeting neddylation might be a promising strategy to reverse lung aging and club cell senescence.
